Globlin

A tray icon that watches your global packages — npm, bun, pnpm, yarn, pipx, uv, scoop, cargo, go, dotnet, PowerShell Gallery, gem, Homebrew, winget, choco, and skills.sh agent skills — and tells you when one falls behind.

globlin.pages.dev

Beta. Globlin is still in beta on every platform: the Windows builds are in daily use, the installer and the ARM64 builds are new, and the macOS and Linux builds are experimental. Please open an issue when something misbehaves.

What it does

Global CLIs rot silently — nothing tells you @salesforce/cli is six versions behind until a command breaks in a way that turns out to be "oh, I'm ancient." Globlin sits in the tray, checks on a schedule, and shows you exactly what's behind, across every package manager you have installed. Open the window to see the lot in one list, filter it by status or by source, tick the ones you want and update them in a batch. It never touches anything on its own unless you turn that on.

On Windows it is one ~3.3 MB .exe with no runtime dependencies — run it portable, or let the per-user installer put it in place. The window is drawn by WebView2, which ships with Windows 11 and with any up-to-date Windows 10. Experimental builds exist for macOS (Apple Silicon) and Linux (deb, rpm, AUR, AppImage).

Install

Every release comes two ways, each for x64 and for Windows on ARM (Snapdragon and other ARM64 laptops):

• Installer — globlin-setup-x64.exe or globlin-setup-arm64.exe. Installs for your user only, no administrator prompt, into %LOCALAPPDATA%\Programs\Globlin; adds a Start menu entry, an entry in Settings → Apps to uninstall it from, and optionally a desktop shortcut and Run when I sign in.
• Portable — globlin.exe or globlin-arm64.exe. Run it; nothing to install, nothing to unzip. It keeps its config next to itself, so you can move the .exe anywhere and it keeps working.

Both update themselves the same way. Right-click the tray icon and tick Run at startup if you want it running every time you log in.

macOS (experimental)

Apple Silicon (M1 and later), macOS 11 or newer. The app is signed ad hoc, not notarised, so macOS asks you to allow it once:

1. Download globlin-macos-apple-silicon.zip.

2. Unzip it and drag Globlin.app into Applications.

3. Open Globlin.app. macOS answers "Globlin" Not Opened — Apple could not verify…; choose Done, not Move to Trash.

4. Open System Settings → Privacy & Security, scroll to the bottom and choose Open Anyway next to Globlin, then confirm. The button only shows for about an hour after the blocked launch. If it is not there, run this once in Terminal and open the app again:

   xattr -dr com.apple.quarantine /Applications/Globlin.app

5. Globlin now sits in the menu bar at the top right. While its window is open it also shows in the Dock and in ⌘-Tab; closing the window sends it back to the menu bar only.

6. Optional: allow its notifications under System Settings → Notifications → Globlin, and tick Run at startup in the window's Settings or the menu.

After that it updates itself like the Windows builds — no need to repeat the steps. Its settings and logs are in ~/Library/Application Support/globlin/; Run at startup writes ~/Library/LaunchAgents/dev.globlin.app.plist. Homebrew packages are compared with your local taps, so run brew update now and then. It is new and tested on one Mac so far — please open an issue when something misbehaves.

Linux (experimental)

A .deb for Debian and Ubuntu (globlin-amd64.deb, globlin-arm64.deb) and an .rpm for Fedora, openSUSE and friends (globlin-x86_64.rpm, globlin-aarch64.rpm):

sudo apt install ./globlin-amd64.deb      # Debian 12+, Ubuntu 22.04+
sudo dnf install ./globlin-x86_64.rpm     # Fedora
yay -S globlin-bin                        # Arch, from the AUR

Or take the AppImage (globlin-x86_64.AppImage, globlin-aarch64.AppImage) — one file for any distribution, and the only Linux build that updates itself:

mkdir -p ~/Applications && cd ~/Applications
curl -LO https://github.com/TOR968/Globlin/releases/latest/download/globlin-x86_64.AppImage
chmod +x globlin-x86_64.AppImage && ./globlin-x86_64.AppImage

It is a thin AppImage: it carries Globlin, its desktop file and its icons, and uses the WebKitGTK 4.1, GTK 3 and Ayatana AppIndicator libraries already on the system (webkit2gtk-4.1 and libayatana-appindicator on Arch). Keep it in a folder you can write to — an update replaces the file in place.

Until globlin-bin is published in the AUR, every release also carries the same PKGBUILD with its version and checksums filled in:

curl -L -o PKGBUILD https://github.com/TOR968/Globlin/releases/latest/download/globlin-bin.PKGBUILD
makepkg -si

The package pulls in WebKitGTK 4.1 and the Ayatana AppIndicator library. GNOME shows tray icons only with the AppIndicator and KStatusNotifierItem Support extension; KDE, Xfce, Cinnamon and most other desktops show them out of the box. On Linux the tray icon opens its menu on any click — pick Open Globlin for the window. A packaged Globlin does not update itself: install the new package from the release page. The AppImage does, like the Windows and macOS builds. Settings and logs live in ~/.local/share/globlin/; Run at startup writes ~/.config/autostart/globlin.desktop.

If Windows Defender flags the download — what it was, and what fixed it

Releases up to v0.2.7 were flagged by a few engines, and Defender quarantined the download as Trojan:Win32/Wacatac.B!ml. The !ml suffix is the tell: no signature matched, a machine-learning model guessed.

The cause was not what Globlin does. A scanner never runs the file — it reads its shape. The release profile was tuned for a small binary, which produced 1.7 MB of unusually dense code, and small dense executables are what packed malware looks like. Nothing here was packed, compressed or hidden; it merely resembled something that is.

Building with a conventional profile settled it: that took the binary from 1.7 MB to 2.8 MB, and three of the four engines stopped objecting. The identical source, built the size-tuned way, still draws them — that comparison and its numbers are in docs/DEVELOPMENT.md. It has grown since — the package-list window links WebView2's glue in — and ships at about 3.3 MB today, which moves it further from the shape that was flagged, not closer.

Microsoft flags some builds and not others, because an unsigned binary of this shape sits close to the model's line. The installers are a separate case: every release, three or four machine-learning engines (Arctic Wolf, DeepInstinct, SecureAge, Skyhigh) flag globlin-setup-*.exe while the portable .exe beside it scans clean. They object to the unsigned Inno Setup wrapper — a program that unpacks and starts another program — not to Globlin; an installer built without compression drew the same verdicts. If yours objects:

1. Update your definitions from an elevated PowerShell and rescan. Microsoft has reviewed Globlin before and removed the detection on request.

   Update-MpSignature

2. Check the hash and the signature. Every release publishes SHA256SUMS, the SHA-256 of every file in it, and SHA256SUMS.minisig, a minisign signature of that list by the Globlin release key. Run Get-FileHash on your download and find the same hash in SHA256SUMS — a match means nothing altered the download. The signature proves the list came from this project's release pipeline: minisign -Vm SHA256SUMS -P RWTTLQhyI4Bn/MclkJqsthxavfiFPGVos6b7/d9keFthKYcrAmvZ31V+. The release notes open with the exact commands.

3. Read the VirusTotal report linked from that release's notes. CI uploads every build as it is published, so you get the full engine spread rather than one engine's guess.

4. Build it yourself — see Building from source below. The source is all here and cargo build --release is the whole of it.

Using it

Starting Globlin yourself — from the Start menu, a pinned icon or the .exe — opens the window, or brings it forward when Globlin is already running; started by Run at startup it stays quietly in the tray. After that, click the tray icon or one of its notifications, or pick Open Globlin from the right-click menu:

The window puts updates first:

• The hero card says what needs doing — 3 updates available, and which sources they come from — with Update all (N) beside it. Under it the outdated packages are grouped by source; each group collapses, has its own Update N button, and shows five rows until you ask for the rest with Show N more. Tick rows and Update selected runs just those, as one queue.
• Everything else sits below as one tile per source with its count — 11 current, 2 current · 1 ignored. Click a tile to open that source's full list. The heading only says Everything else is current when it is: a package the registry hasn't answered for shows ? and is counted as not checked, never as fine. A package installed from a git URL, a local folder, npm link or a private registry also shows ?: Globlin never compares it with the public registry, so a public package with the same name can never be offered as its update.
• Search narrows every list as you type, and the chips above the card — All, Updates, Up to date, Not checked, Ignored — filter by status. While either is active, every source with a match opens on its own.
• Per row: Update runs npm install -g <name>@latest (or the pnpm/yarn/bun equivalent) with no console window, then re-checks. Ignore removes it from checks and from Update all without touching the network — Unignore and it's re-checked immediately. Uninstall arms into a Confirm button and then removes the package with npm uninstall -g <name> (or the equivalent). The two clicks are the confirmation; there is no dialog.

• While a queue runs the hero card turns into its progress: Updating 7 of 12, a bar split into done, failed and running, and the queue grouped by source. The group that is running opens by itself, so does one with a failure, and the rest fold to one line saying done or queued.
• If npm 12 refuses an update because a dependency wants to run install scripts you have not approved, Globlin opens its window with the list of packages and the exact scripts. Allow and update adds those exact versions to allow-scripts in your user .npmrc and runs the update again; Not now leaves the old version in place. Approve npm install scripts automatically, in Settings, skips the dialog and allows them straight away. It is off by default, because with it on any dependency's install scripts run without you seeing them. If the retry is refused again, the dialog opens as usual.
• winget and choco update and uninstall like everything else, but may ask for an administrator. Globlin runs unelevated and never elevates itself. winget runs as you: a per-user package updates silently, and a machine-wide installer raises its own Windows prompt. choco always needs an administrator, so each choco update or uninstall asks once, through the standard Windows prompt — five choco packages in Update all means five prompts. Saying No fails that one package and the queue moves on. One administrator prompt for all choco updates, in Settings, runs every choco package in the batch through a single prompt instead; their rows then finish together at the end, and No fails all of them. One administrator prompt for all winget updates does the same for winget: one prompt, after which every winget update in the batch runs as administrator, so no installer is left waiting on a prompt nobody sees. A few installers refuse to run as administrator and then fail. Their rows, groups and Settings switches carry a small may ask for admin / asks for admin tag; hover it for the reason. Globlin's own entry is left out of the winget list, so it can't uninstall itself.
• Not every refused update is a failure. When winget says no update applies to this system (Docker Desktop on an unsupported setup, for instance) or the administrator prompt was cancelled, the row reads skipped and the notification names the reason instead of reporting a failure. When an installer is refused because another installation is still running, Globlin tries that package once more at the end of the batch. When a winget update fails while programs from its folder are running (Git's installer and an open terminal, or ChatGPT's background service), the row reads in use: bash ×9 and offers Close & update: it closes those programs without saving anything — stopping a service asks for an administrator — updates, and starts again the programs you had open. It never runs on its own, not even from Update all. A winget package whose installed version winget itself reports as Unknown reads not checked, since winget refuses to upgrade it anyway. An entry winget only found in Installed apps with no version at all (Steam games, for one) is left out of the list: its own launcher keeps it current.
• A desktop notification only fires when the set of outdated packages changes, so it won't nag about the same three packages every six hours.

Settings, behind the button at the top right, holds the rest: Run at startup, Monochrome tray icon, Approve npm install scripts automatically, Update Globlin automatically (greyed out with the manager's name when winget or the installer keeps Globlin up to date) and, when a release is waiting, Update now. Under Sources every package manager this platform can have gets a switch and a one-line status — 13 packages · 2 updates, No global packages, Off. Switching one goes into globlin.json at once; a fresh check follows two seconds after the last switch, so flipping several costs one check. Diagnostics opens the last log; About shows the version and links to Patreon, as does Support on Patreon beside Open last log at the foot of the window. Source code under About and GitHub in the footer open the repository.

The tray menu stays short — the list lives in the window:

While a batch runs, the menu also shows up to seven rows around the package being updated and one … N more line; the full queue is in the window.

Sources

Source	Where the list comes from	Where latest comes from	Update
npm	npm ls -g --json --depth=0	registry.npmjs.org	npm install -g <name>@latest
bun	the global package.json + node_modules	registry.npmjs.org	bun add -g <name>@latest
pnpm	pnpm ls -g --json --depth=0	registry.npmjs.org	pnpm add -g <name>@latest
yarn	yarn global dir + node_modules	registry.npmjs.org	yarn global add <name>@latest
pipx	pipx list --short	the project's PyPI release feed	pipx upgrade <name>
uv	uv tool list	uv tool list --outdated	uv tool upgrade <name>
scoop	apps\*\current\manifest.json	the manifest in the app's local bucket	scoop update <name>
cargo	cargo install --list	crates.io, one request for every crate	cargo install <name>
go	go version -m over the Go bin directory	go list -m <module>@latest	go install <package>@latest
dotnet	dotnet tool list --global	the NuGet flat-container index	dotnet tool update --global <name>
psgallery	Get-InstalledModule	the PowerShell Gallery's package redirect	Update-Module -Scope CurrentUser
gem	gem list --local	gem outdated	gem update <name>
brew	brew info --json=v2 --installed (formulae and casks)	the same reply — brew's outdated flag	brew upgrade <name>
winget	winget list	winget's own Available column	winget upgrade --id <id> --exact --silent
choco	choco list -r + choco outdated -r	choco's own report	choco upgrade <name> -y, elevated
skills	the skills.sh lock file (~/.agents/.skill-lock.json)	the skills.sh CLI's own update, run on every check	npx --yes skills update <name> -g -y

Everything except psgallery, winget and choco is on by default. A source whose CLI isn't installed simply reports nothing — it is not an error, not even when none of them is installed, and one broken source never sinks the others. psgallery is off because it has to start PowerShell on every check, which costs about a second; winget and choco are off because both are slower to list and updating them can raise administrator prompts. Turn any of them on from the window's Settings, or in globlin.json.

yarn means yarn classic (v1). Yarn 2+ removed yarn global entirely; on a Berry install the source reports zero packages and says so in the log.

pipx and uv, not pip. pip list reports every library in whichever interpreter happens to be first on PATH — mostly transitive dependencies, and often not the environment your shell is in. pipx and uv tool give each CLI its own venv, so their listings name exactly the tools you installed globally, and neither needs elevation to upgrade one. A PyPI, NuGet or Gallery version that is not a plain run of numbers (1.0.0rc1, 1.0.0.post1) is reported as not checked rather than guessed at.

scoop is compared against your local buckets. Globlin reads the same bucket manifests scoop status reads and never runs scoop update for you, so an app is only as current as your last bucket refresh. Apps installed with scoop install -g live under C:\ProgramData\scoop and are not listed.

brew is compared against your local taps, like scoop against its buckets: Globlin never runs brew update, so a formula is only as current as your last brew update (which brew runs on its own before most installs). Both formulae and casks are listed.

cargo and go build from source. Their Update runs a real compile, which can take minutes; the row keeps spinning until it finishes. Go has no uninstall command, so Uninstall on a go row deletes the binary from your Go bin directory itself, after finding it with go version -m, and refuses to touch anything outside that directory.

The same package can be installed under several managers and stays distinguishable: the window shows the source in its own column, and menu and notification text suffix it — typescript (pnpm).

Icon states

The tray icon is drawn from code, not an image file, so its colour always matches what it's telling you:

	State	Meaning
	Idle — emerald	everything installed is current
	Updates — amber	one or more packages are behind
	Error — red	the last check failed, a source could not be listed, or a registry could not be reached (the notification and Open last log name it)
	Busy — sky blue	a check or an update is running, filling like a glass

If the coloured goblin stands out too much next to the system icons, switch on Monochrome tray icon in the window's Settings. The goblin is then drawn in one colour with its face cut out — white on a dark taskbar, near-black on a light one, and on macOS a template image the menu bar tints itself. Colour can't carry the state any more, so a dot beside the head means updates are waiting, a dot with an exclamation mark means something went wrong, and while a job runs the dim outline fills solid from the bottom up.

Keeping itself updated

Upgrading from 0.3.x: 0.4.0 changed how updates are signed and named, so a 0.3.x build cannot update itself to it. Install 0.4.0 by hand once — from then on it keeps itself updated as below.

Globlin also checks its own GitHub releases on the same schedule as the package check. The Globlin v<current> submenu names the build that is running, so you can always tell which one is live. When a newer one is published the submenu grows an Update Globlin <current> → <new> row; ticking Auto-update Globlin (or Update Globlin automatically in the window's Settings) installs it unattended the next time one is found, no click needed.

Before installing anything, the download must carry a valid signature by the Globlin release key, whose public half is built into the app, and match its published SHA-256 checksum — a release without a signature is not offered, a mismatch is discarded, and the running app is never touched. The one real failure mode: if Globlin can't write next to itself (installed under Program Files without elevation, or a directory an antivirus is holding open), the install fails. You get one toast about it, not a repeat nag; auto-update stops retrying that build rather than re-downloading it every few hours, and the reason lands in a log you can open from the menu. The row stays, so you can still retry by hand. See docs/DEVELOPMENT.md for exactly how the swap, rollback and restart work.

More

Configuration — globlin.json

The portable Windows build reads it from next to the exe first, otherwise from %LOCALAPPDATA%\globlin\, and writes it back to whichever of those accepts a write. An installed build (the installer or winget) and every macOS and Linux build keep it in the data directory only — %LOCALAPPDATA%\globlin\, ~/Library/Application Support/globlin/ or ~/.local/share/globlin/. Missing keys take their defaults, so a partial file is fine. If the file isn't valid JSON, it's moved to globlin.json.invalid, defaults are used, and a notification says so — your edits are never silently overwritten.

• sources — which package managers to check. Missing keys take their defaults, so an older config file keeps working and simply gains the new sources. See Sources.
• ignore — listed packages still appear in the window with their version, but are never checked, flagged or notified about. npm is ignored by default because updating it on Windows means it rewrites its own shim mid-run; @anthropic-ai/claude-code because it self-updates. An explicit [] is respected.
• last_notified — bookkeeping for the "only notify on change" rule. Clear it to force the next check to notify again.
• npm_cmd — an override, only needed if npm.cmd is somewhere unusual. Left null, PATH is searched, then %APPDATA%\npm\npm.cmd. The file must be called npm (npm.cmd, npm.exe) and must not be a downloaded file still carrying Windows' from the internet mark; otherwise npm is skipped rather than run.
• auto_update — see Keeping itself updated.
• auto_approve_scripts — the Approve npm install scripts automatically switch in the window's Settings; see Using it.
• update_all_on_start — the Update everything when Globlin starts switch in the window's Settings: once the first check after launch finishes, it runs Update all a single time. Ignored packages are skipped, as with the button.
• choco_one_prompt — the One administrator prompt for all choco updates switch in the window's Settings (Windows only); see Using it.
• winget_one_prompt — the One administrator prompt for all winget updates switch in the window's Settings (Windows only); see Using it.
• monochrome_icon — the Monochrome tray icon switch in the window's Settings; see Icon states.
• last_self_notice — the version string of the last self-update failure a toast was already raised for, so retrying the same failing version doesn't notify twice.

Diagnostics & removing it

In %LOCALAPPDATA%\globlin\: last-check.txt (every package from the most recent check with its state — look here first when the window shows something surprising), last-run.log (stdout/stderr of the failed package updates of the most recent batch, written as soon as each one fails, and the reason a source could not be listed, reachable from Open last log), self-update.log (the error from the most recent failed self-update lookup, kept separate so an offline run doesn't overwrite the log Open last log reads), and app.ico (the notification artwork).

To remove an installed Globlin, uninstall it from Settings → Apps; that also removes the Run at startup entry, and leaves %LOCALAPPDATA%\globlin\ (settings and logs) for a reinstall — delete it if you are done for good. To remove the portable one: quit from the tray menu, delete the .exe and its .json, then delete %LOCALAPPDATA%\globlin\. If a self-update was interrupted, globlin.exe.old may still be sitting next to the .exe — safe to delete too. Two optional HKEY_CURRENT_USER cleanups:

• Software\Microsoft\Windows\CurrentVersion\Run → globlin, only if Run at startup was ever enabled.
• Software\Classes\AppUserModelId\Globlin.Tray, created so notifications are attributed to "Globlin" rather than to PowerShell.

Nothing else is written — no service, no scheduled task. The installer adds only its own uninstall entry and shortcuts, and removes them again.

Upgrading from npm-globals-tray: this app was renamed from npm-globals-tray to Globlin. The new build starts fresh with default settings, leaving three harmless leftovers you can delete once you've switched to globlin.exe: the old config file (npm-globals-tray.json), the old data directory (%LOCALAPPDATA%\npm-globals-tray\), and the old Run key value named npm-globals-tray.

Building from source

On Windows, a Rust toolchain (MSVC) plus Microsoft C++ Build Tools and the Windows SDK. On macOS, a Rust toolchain and the Xcode command-line tools. On Debian or Ubuntu, a Rust toolchain plus libgtk-3-dev libayatana-appindicator3-dev libwebkit2gtk-4.1-dev.

cargo build --release

On Windows target/release/globlin.exe is portable — copy it anywhere and run it; it keeps its config next to itself. The macOS .app bundle and the Linux packages are assembled by the scripts in .github/ — see docs/DEVELOPMENT.md.

For architecture notes, the verified environment workarounds, tests, lints, and the CI/release pipeline, see docs/DEVELOPMENT.md.

Code signing policy

The Windows builds are not code-signed, so SmartScreen warns the first time one runs. Free signing through SignPath Foundation was applied for in October 2026 and declined for now: the Foundation signs projects that already have wider public adoption, and Globlin will apply again once it does. Until then, what is signed is the release itself — every file is listed in SHA256SUMS, and that list is signed with the Globlin minisign release key, the same key the app checks before it updates itself (see If Windows Defender flags the download above).

• What is released: only the files .github/workflows/release.yml builds from a tagged commit of this repository on GitHub-hosted runners. Nothing built anywhere else, and no third-party binaries.
• Team roles: committers, reviewers and release approvers — TOR968. Every release is reviewed and merged by hand.
• Multi-factor authentication is required on GitHub for every role.
• Uninstalling: the installer registers an uninstaller under Settings → Apps; the portable build and everything Globlin writes are covered in Diagnostics & removing it above.

Privacy

Globlin has no telemetry, no analytics, no crash reports and no account, and sends no identifier of its own — the one exception, a GitHub token you already set, is explained under Skill lookups below. It goes on the network only to do what it is for, and every request it makes names Globlin in its user agent:

• Version lookups: the names of your installed packages are sent to the public registry of their package manager — registry.npmjs.org (npm, bun, pnpm, yarn), pypi.org (pipx), crates.io (cargo), api.nuget.org (dotnet) and www.powershellgallery.com (PowerShell Gallery). Switching a source off in Settings stops its lookups, and ignored packages are never looked up. An npm, bun, pnpm or yarn package installed from git, a local path, a link or a private registry is never sent to the public registry.
• Skill lookups: for skills installed with skills.sh, every check runs npx skills update <names> -g -y, which installs whatever has fallen behind. The skills.sh CLI does the network part: it reads each repository's file tree from api.github.com, falls back to GITHUB_TOKEN, GH_TOKEN or gh auth token when the anonymous limit is spent, and reports usage to skills.sh's own telemetry. Ignored skills are never named to it. Switching the skills source off stops these runs.
• Its own updates: github.com/TOR968/globlin/releases/latest is asked which release is the latest (only the redirect is read), and an update is downloaded from GitHub's release storage. Builds owned by winget or a system package manager skip this.
• The package managers themselves contact their own servers when Globlin runs their list, outdated, update and uninstall commands; what they send is governed by their own privacy policies.
